DRIVING F SPINNING SPINDLES.

Application filed May 11,

To all whom t may concern.'

Be it known that JAMES CoNsTABLE LESLIE,

a subject of the King of Great Britain and Ireland, residing at Dundee, Scotland, have invented certain new and useful Improvements in the Driving of Spinning Spindles, of which the following is a specification.

This invention relates to the driving of spinning spindles of the kind in which the spindle terminates a short way below the neck rail and is well suited for use in connection with the spindle which is the subject of my prior U. S. A. Patent No. 993080.

The object of this invention is to do away with the usual tin cylinder, jockey cylinder, and list bands and also to reduce the driving power required; the invention also permits of a spinning frame being provided which requires less floor space than the ordinary frame.

According to this invention the spindle is driven by a disc mounted on it below the neck rail, which disc is driven by a friction disc mounted on and driven by a shaft lo- 35 cated beneath the neck rail. Means may be provided for throwing the friction disc in and out of operation.

The following description and accompanying drawings show one manner of carrying out the invention.

Figure 1 is a front elevational section on the lines A B Figure 2.

Figure 2 is an end view of Figure 1 part in section.

Figure 3 is a detail.

The rail 1 is of box form. The spindle 2 is shown carried in a ball bearing neck 3, fitted in the upper flange of the rail, and terminates just below the neck. Mounted on the lower end of the spindle is a disc or warve 4, which, when rotated, rotates the spindle. The warve may be faced with leather or other material or may have a metal face. Longitudinally of the rail and below the upper flange is mounted, in suitable bearings, a shaft 5. A feather, or feathers 6 is or are, secured in the shaft to drive a friction disc 7 having a boss 8 and driving face 9 of leather or other suitablematerial. If desired the driving face may be of metal. The face 9 is pressed normally into Contact with the warve 4 by means of a spring 10 mounted on the boss 8 which is 1921. sei-iai No. 468,609.

kept in compression by means of a collar l1 secured on the shaft 5 by a grub screw or 55 other means.

'A .front plate 12 encloses the mechanism within the box rail 1 and also serves to carry a device for throwing the disc 7 in and out of operation. This device consists of a bearing 18 provided with a fiange 14 secured to the plate by screws 15, the bearing passing through the plate as far as permitted by the flange. An aXle 16, provided with a suitable handle 17, is carried in the bearing and has secured to its end a rectangular plate 18 (as shown in Figure 3) The longer axis of the plate is normally vertical, which allows the disc 7 to be in contact with the warve, but when it is turned through 90o it 70 presses the disc out of contact with the warve and the spindle comes to rest.

rlhe shaft may be driven by any suitable means, such as shaft, pulley and belt located in a suitable position in the spinning frame and the shaft (carrying the friction disc) may, instead of running the whole length of the frame, be formed in sections to enable a limited number, instead of all of the spindles being thrown out of operation when repairs are required.

The shafts of a number of frames may be driven by one shaft at right angles to the disc shafts and running the whole length of the row of frames. Friction gearing could be employed and so arranged as to vary the speed of any particular disc shaft or shafts.

If desired the friction faces of the warve 4 and disc 7 may be bevelled.

It will be seen that by the use of this in 90 vention the tin drum, list bands, whorls and long spindles will be done away with and that the spindles can be stopped when required without the attendant having to hold the flier or throw off the band.

The invention may be used in connection with any kind of spinning, other than flyer spinning, to which it is applicable.

I claim In a spinning machine, the combination comprising a box rail the upper flange of which serves as a neck rail, spindles rotatably mounted in said neck rail, a drive shaft longitudinally disposed within said bcX rail, friction discs secured by feathers to said shaft and arranged to drive said spindles, springs normally holding'said dises in In testimony whereof I have hereunto set Contact With said spindles, a Jfront plate my hand in presence of two subscribing joining the flanges of said bo-X rail to en- Witnesses.
